This invention relates to improvements in wrapping machines.

My improvements are particularly de-l signed by me for use on wrapping machines of the type illustrated in the application of Harry L. Johnson, Ser. No. 5257, filed Jan. 30, 1915, and I have illustrated the same as I have embodied it in such a machine. My

and desirable for use in other relations.

The main objects of this invention are: First, to provide an improved sealing means for wrappingI machines which is very effective in sealing waxed wrappers.

vof a structure j Fig. VII is a side elevation j VIII is an enlarged detail view on Second, to provide an improved sealing means for wrapping machines which is adapted for use in sealing packages of Iconsiderable variation in size without special adjustment. l

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

Il accomplish the lobjects of my invention by thedevices and means described in the following specification. The invention is clearly defined and pointed' out .in the claims.

A structure which' is a preferred embodiment of my invention is clearly-illustrated in the accompanying drawing, forming a part of-this specification, in `which:

Figure I is a detail longitudinal section embodying the features of my invention taken on a line. corresponding to ,line 1-1 of Fig. II..

Fig. II is a detail plan view.

Fig..III is an enlarged detail side elevation of one of my improved heating plates.

of Calhoun, State of a however, readily adapted l oteld on the supporting Patented Jan. 217, 1920.

f Application filed July 27, 1918. Serial No. 246,993.

In` the drawing I haveillustrated only such parts` of a wrapping machine as. seem to me desirable to illustrate an adaptation\ ofy my improvements.

In the drawing similarreference characters refer to similar parts .throughout then several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring `to thedrawing, 1 represents the main frame of the machine, whichiis provided with aconveyer comprising a coiiveyer chain 2 supported at vits rear end by the sprocket 3 and provided with flights il. The articles advanced by the conveyer are carried along on the conveyer ways 5 by the flights which project upwardly between the ways on the upper reach of the conveyer chain. Details of the wrapping means are shown' at 6. The wrapping means are not fullyshown and described as they form no part of my present invention.

A' satisfactory wrapping means'is shown ,in

the application for patent hereinbefore referred to. i y

As the packages are carried along by the conveyer they arec carried between the sealing plates 7 shown by dotted lines in Fig. II supported in an opposed relation.

The sealing Kplates carry heating` means, rshown conventionally at 8, the plates illustrated being provided with electrical heatingv units. f

The electrical connections are not illus-A trated as they will be readily understood b-y those skilled in y the art to which this invention relates. f

Each plate is supported at its 'front end by pivots V9 disposed through ears 10 on the p ate and coacting ears l10n the forward end of the supporting frame 12. This supportinvr frame is mounted onthe lia-nger 13 carried by the cross bar 14. The ofthe sealing plate is held yieldingly inward by means of the lever 15 which is pivframe at V1.6 and pro- `vided with anjnturned arm 17 engaging the plate and with an inwardly projecting rear end arm 18 having weights 19 adjustable thereon for regulating the pressure with which the plates are urged inwardly.

yAs the packages are carried along between l the plates bythe flights the-plates yieldingly engage the packages so as to eectively seal tage as packages vary in size or on accountv of distortion or variations in dimensions.

y my improvements such variations are accommodatedand atl the same effectively time effective sealing had. p

The packages are passed bythe conveyer to the delivery belts 20l and by them to the delivery table 21. These parts are s hown in the application referred to and therefore are not further described herein.

- The driving means for the conveyer arenot described as such driving means form nov part of this invention.

In the` modification shown in Figs. VI,- VII and VIII the heating plate 22 is supported by the bar 23 mounted on the hanger 18 and-provided with inwardly projectlng arms 24between which the heating member v1s supported by the screws 25 engaging the slots 26 permitting limited movement.

Springs- 27 carried by the bar 23` urge the heating members yieldingly inward.

I have not attempted to illustrate other adaptations 'of my improved sealing means which I contemplate as I believe the disclosure made will enable those skilled in the art to embody or adapt the same as may Qbe desired. s f

Having thus described my invention, what I claim as new and'desire to secure by Letters Patent, is: i

1. In a wrapping machine, the combina-V tion of tion of a conveyer, sealing plates disposed in an opposed relation at the sides of the conveyer to act on the packages carried between them vby the conveyer, hangers, sealing plate supporting frames on said hangers, the front ends of said plates being pivoted on said frames, levers for urging the rear ends of said platesy yieldingly inward pivoted on said frames and having arms eX- tending under the conveyer, weights adjustA able on said arms, and heating means for said plates carried thereby.

n a-wrapping machine, the combinaa conveyer, a sealing plate disposed to act .on the packages carried along thereby, a hanger, .a sealing plate supporting frame carried thereby, the front end of said heating plate being .pivotally mounted on said frame, a llever pivotally mounted on said frame to acton the rear end of said plate, and a weight adjustable 'on said lever, all coacting for the purpose specified. 3 In a wrapping machine, the combination of a conveyer, in an opposed relation to act on the packages carried between said plates beingpivotallyfmounted at their` front ends, pivoted levers for urging the rear ends of-said plates yieldingly inward, actuating weights adjustable on said levers7 and yheating means for said plates carried thereby. p

In witness whereof I have hereunto setiny hand and seal in the presence ,of two witnesses.
